RAIL-CHAIR.

Application lcd April 28, 1913.

To all whom t may concern Be it known that l, AUGUs'r G. LIEB- MANN,citizen of the United States, residing at Butte, in the county ofSilverbow and State of Montana, have invented certain new and usefulImprovements in Rail- Chairs, of which the following is a specification.

This invention relates to railway track appliance and particularly torail chairs, and means for holding the rail in place therein andadjusting the rail.

When rails are held to the ties merely by spikes engaging the baseflanges of the rail, the thrust incident to the passage of a train tendsconstantly to loosen or withdraw the spikes. The vertical thrust of therolling stock tends to force the rail into the tie crushing and breakingthe fibers of the same. The lateral thrust tends to shear the spikes orloosen them, and the tipping thrust tends to tip the rails upon one sideedge of the base flange and raise the other side edge, thus withdrawingthe spikes. As a consequence, there is constant necessity of redrivingand renewing spikes and ties. Furthermore, where spikes are used anydepression or elevation of one portion of a rail or section of a trackunder, for instance, the action of frost or thaw, tends to cause eithera withdrawal of the spikes, or the base flange of the rail will shear ifthe spikes can not be withdrawn.

The primary object of the present invention is the provision of a verysimple form of rail chair in which the rail is to be seated which may bereadily formed by rolling and pressing, and in which to this end thebody of the chair is made from a deformed I- beam section.

rfhe further object is to so form a chair that the rail will be fullysupported against vertical or lateral thrust or any tipping action. Thechair with oppositely disposed abutments between which the rail isseated permits the use of rail clamping wedges between the abutments andthe brace or lining plates of the rail, these rail clamping wedgespermitting the rail to be laterally adjusted between said abutments sothat' the rails of the track may be brought to gage and readily kept ingage.

The still further object is to so form a chair that the rail may bereadily adjusted Specification of Letters Patent.

vertically by means of shims and then held rigidly in its adjustedposition.

Another obj ect is to so form the chair that the clamping wedges wherebythe rail is held shall be prevented from any vertical displacement.

Another object is to provide a type of chair and rail clamping meansparticularly adapted for use on southern lines with well drainedsub-grade and rock ballast, and for either freight or passenger trafhc.

Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings wherein:

Figure l is a perspective of a tie and rail and the improved rail chairapplied thereto; F ig. 2 is a plan view partly in section of theconstruction shown in Fig. l; Fig. 3 is a vertical sectional view on theline 2)-3 of Fig. 2; Fig. l is a transverse section of the structuralmember from which the chair is made showing in dotted lines the way thatthe member is pressed in order to form the complete chair.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

Referring to these drawings, A designates a tie and B the rail. rlherail B may be of any type but as shown is of a standard type. Theimproved chair comprises a bed plate 2 having a width preferably that ofthe tie and resting firmly on the upper face thereof. Extendingtransversely across the bed plate and parallel to the direction of therail are the abutments 3 which are spaced from each other a distanceslightly greater than the width of the rail base. These abutments extendvertically to a height nearly equal to the under face of the head of therail` and are then bent inwardly at right angles to form overhanginglips 4L. The bed plate with its abutments 3 is preferably formed from anI-beam section. The metal of the plate is first rolled in the form of anI-beam and then the flanges of the I-beam on one side are bent outwardlyat right angles to the flanges on the opposite side in the mannerillustrated in Fig. 4, the dotted lines showing the manner in which theflanges are bent so as to form a bed plate. It will be seen that thisbed plate may be easily formed by rolling and'pressing. and is animportant feature in the practical construction of the chair. y

Disposed on each side againstthe web of the rail are brace or liningplates 5. Each of these plates has an inner face adapted-to lit the webof the rail and upper and lower fianges each having a beveled faceadapted to fit the beveled face of the base and the under face of thehead of the rail."

Disposed between the abutments 3 and the' lining plates-"5` are the''wooden wedges '6.

These wedges are' longitudinally tapered upon their outerf erJv innerAfacesfand-I upon their' lower or upper faces andsnugly nt inI thespace-"- deiined by the abutments,` the base flange of the rail and thel' outer faces of the liningplates Eachfwedge isfrabbeted upon itslciwer 'facey asatl'soI` as to t overy the lower yflange of the"corresponding cheaply made b'ut is well adapted 'i for usel on lines inf climates where the line is well drained. It will be obvious; however,that these wedges' may always be kept tight by` th'e track* walker withyvery little trouble. It" often occurs'I that theV railv mustl beadjusted vertically in order to keep the line of track level as where'one portionoff the track has beenlifted'by frost and itis necessary toadjust `the adjacent portions' of 'the` track. This 'may be readily*a'cc'omplislied'by' looseningl the" wedge's 6 andthen' inserting' a shim9 vbetween the base of the rail aridi they raill After'thefshim isdriven in* place',- the wedges 6* are again' seatI on the' bedplate.

It will' be particularly notedf fromv Figs'.

beingparallel to the rail and to each other have a tendency to stiffenthe bed plate at points on each side of the rail where the stift enin'gis most desired,` andfurther' that any slight buckling downwardly ofthebed-plate under rail pressure will cause said abutments to curve or bendslightly inward toward the rail, and thus press the wedges into thelining plates and hold said'wedges in a xedposition;

Particular attention may be calledin connection with my improvedra-ilichair to the oiiicial report of the Bloclr'Sig'nal and TrainQontrol Board of; the Interstate vCommerce Gommissiong-vthis reportbeing dated J une 29, 1912, wherein certain requirements'are laid `downfor rail supports andwherein the board"says:'LAQi fundamental defectinde-` sign which is most apparent is the failureY to're'alize andappreciate the overturning movementf du'e to l the wheel flange'pressure against'the head oftherail.IVA ltis not sufficient that the tieshould support the'vertical loads `and" resist'` directly horizontalthrusts and thetendency of the trackl to more later! allyfandlongitudinally, but theo verturning movement must be'l'r'esisted. thetie`n1'ay properly* support the stresses transmitted to itt by therail,l asu'itable fasteni/iig offthe rails to" heties is most essentialFurther the reportstates that""under conditions existingina largepreportionof the'railr'oads in thiscountry the means of adjustment ofrail=to`tie must be su'chas to admit of blocking up or4^ shimming.7 Theboard further says that adequate' means should be' provided forshimining or tor widenii'igfgage andk this-means should not involve lostmotion and change of adjust'- ment. It ispointedouttliat the improvedrailchair, as heretofore described, conforms to allof the requirementsreferred to in this report and at the same time the fastenings are notof a complicated'nature andfthat-the chairs may be made relatively icheap. i
